Before changing any certificate settings, you must make sure that you really trust the owner of the certificate and that the certificate really belongs to the listed owner. Digital signature You can make digital signatures with your phone. This feature requires support from your SIM card. The signature can be traced back to you via the private key on the security module and the user certificate that was used to perform the signature. Using the digital signature can be the same as signing your name to a paper bill, contract or other document. To make a digital signature, select a link on a page, for example, the title of the book you want to buy and its price. The text to sign (possibly including amount, date, etc.) will be shown. Check that the header text is Read and that the digital signature icon is shown. Note: If the digital signature icon does not appear, there is a security breach, and you should not enter any personal data such as your signing PIN. To sign the text, read all of the text first and then you can select Sign. Note: The text may not fit within a single screen. Therefore, make sure to scroll through and read all of the text before signing. Select the user certificate you want to use. Key in the signing PIN (see General information on page 13) and press OK. The digital signature icon will disappear, and the service may display a confirmation of your purchase. Copyright © 2005 Nokia. All rights reserved. 131
